'shoemakers hammers or similar tools, and

relates particularly to improved means for detachably connecting the handle to the iii 5 body of the hammer.

An object of this invention is the provision of a tool body, and one in which a recess is formed to receive a reduced neck of i the handle ofthe tool, a cover plate'being provided for engagement against the recessed side; of the bodyto close the recess. therein and detachably connectthe. handle to the head. i

Another object of this invention is the provision of improved means for attaching the handle of the tool to the body thereof,

the body being provided in one side with a recess, the base wall of which is curved and the side walls of which converge toward the open side of the body, the handle of the tool being provided with a reduced neck which is oval-shaped in cro'ss secti0n so that when the neck of the handle is engaged in the recess in the body, the sides of the neck are disposed behind the outer ends of the converged side walls of the recess, whereby the handle can only be removed by rotating the handle to dispose the smallest dimension of the neck in alinement with the open end of the recess.

With the above and other objects in view, my invention consists in the novel-construction, combination, and arrangement of\parts to be hereinafter more fully described,

claimed, and illustrated in the accompanying drawing, in Which,

Figure 1 is a sideelevational view of my improved hammer with the cover plate partly broken away; Fig. 2 is a perspective 'yiew of the body of the hammer with the cover plate iremoved; Fig. 3 is a perspective .view of theieover plate; and Fig. i is a sectional viewon the line 4-4 0* Fig. 1.

Referring more particularly to the-drawing, the numeral 1 designates the body of the hammer which is providedin one side thereof with a countersunk portion 2, and

a recess 3, the open side of which communicates with the countersunk portion-of the body. The base wall of the recess is curved as at 4, and the side walls thereof are converged as at 5, toward the open end of the recessso that the distance between the side walls at their extremities is less thanthe greater dimension than the neck 7. lhe redueed neck of the handle is substantially oval-shaped in cross-section, and the greatest dimension thereof is of relatively greater width than the distance between the eX- tremities of the side walls 5 of the recess,

and to connect the handle to the body of the hammer, the reduced neck must be disposed so that the narrowest dimension thereof is 1 engaged in the recess, whereupon the hendle is rotated to dispose the widest or greatest dimension of the neck across the recess so that the extremities of the side walls 5 engage over the sides of the neck to provide a-tight joint between the body of the hammer and the handle. it will be seen that the enlarged head 8 on the extremity of the handle engages one face of the body of the hammer and the body portion of the handle engages against the opposite face of the body of the hammer so that longitudinal movement of the body with relation to the handle is prevented. To prevent rotation of the handle with relation to the body of the tool, a cover plate 9 is disposed within the countersunk portion 2 of the body 1, the cover plate being provided with an inwardly extending curved enlargement 10 to engage against the neck of the hammer at the open side of the recess, and the cover plate 9 is secured to the body by suitable screws or the tool is prevented.

While I have shown the attaching means as used. in connection with a hammer, in the accompanying drawing, it will be readily understood that other tools, such as axes or the like, may be readily provided with my improved attaching means and that all danger of slipping of a toolfrom a handle constructed in accordance with my inven-, tion, is obviated.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent, is v l. A tool comprising a body and a handle, said body having an eye recess formed in one side thereof, the side wall of which is convexly curved in the direction of the axis of the eye, the wall of said recess also converging toward the side opening thereof whereby to form a relatively contracted throat, the handle being provided with a neck, the neck being longitudinally concavely curved to accord with the convex curvature of the recess wall, the diameter of the neck at its greatest dimension being greater than the width of the throat of the recess, whereby the narrowest-dimension of the neck must be introduced through the open side of the body andthe handle turned to dispose the neck entirely withinthe recess, and a cover plate detachably connected to the open side of the body for engagement against the neck of the handle, whereby to prevent the handle from turning within the the body having a countersink in one side face and an eye recess extending inward" said throat, whereby the narrower dimen- I I sion of the neck must be introduced through the throat of the recess and the handle turned. to dispose the neck entirely within the recess, a cover plate adapted to fit said countersink and havinga thickened middle portion adapted to extend into said throat, the inner face of the thickened middle portion being concavely curved, and means holding the handle detachably in engagement with the body.

3. A tool head having an eye of substantially ellipticalform in plan, the wall of the eye being convexly curved longitudinally, the eye opening upon the face of the head, said opening being narrower than the major axis of the eye, whereby to form a relatively contracted throat, and a cover plate detachably held against the side face of the head and having a thickened middle portion insertible into said throat.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses] AARON DEWINSKY.
